The 4th industrial revolution came deep into family life and changed the way of housework and care. The change in the family caused by the technological change of the 4th industrial revolution is remarkable in terms of socialization of housework. In this study, the socialization of housework, which is accelerating in the era of the 4th industrial revolution, was examined focusing on the change in the aspect of "household service" through the "platform". Since 2015, when technological changes in the 4th industrial revolution began to decline, related newspaper articles were extracted for daily and economic newspapers nationwide and analyzed big data. The results of big data analysis show that the platform economy using the 4th industrial revolution technology is rapidly spreading the socialization of housework not only at the business level but also at the public policy level. It has been confirmed that support for household services through the platform is growing into a new business area of companies, and at the public policy level, it is being treated as an important policy task in supporting work-family balance or responding to infectious diseases. This study is meaningful in that it provided an opportunity to reflect on the roles and tasks of the family, market, and state for housework and care in the future through changes in housework and care caused by the 4th industrial revolution technology.

The purposes of this study were firstly to explore the practical implications that of 'low carbon and green growth' policy, which is at the top of the Government's agenda provides to family, and secondly to propose some visions for a future based on those implications. The results of this study were as follows: Firstly, in terms of a global perspective, there is now a worldwide trend towards the adoption of 'low carbon and green growth' policies. Secondly, the Government-driven 'green growth policy' demands a total transformation, that is, revolution, not only in terms of our industries, but also in terms of our mentality and ordinary life. Thirdly, the driving force for this life revolution lies in having green life style, and the family is the primary agent for making the green life style a practical reality.

In this paper we generalize 3-dimensional Bour's Theorem to the case of 4-dimension. We proved that a helicoidal surface in $\mathbb{R}^4$ is isometric to a family of surfaces of revolution in $\mathbb{R}^4$ in such a way that helices on the helicoidal surface correspond to parallel circles on the surfaces of revolution. Moreover, if the surfaces are required further to have the same Gauss map, then they are hyperplanar and minimal. Parametrizations for such minimal surfaces are given explicitly.

This study forecasts the outlook 10 years from now regarding domestic labor and caregiving by the Baby Boomer generation and the preparations needed in the context of the Fourth Industrial Revolution. The scenario-planning method was used to explore changing trends in domestic labor and caregiving, the rationale for which has been questioned by both seniors and family welfare experts. Based on the results of the survey and our researchers' opinions, it was concluded that the changing trends were caused by two factors: the probability of alterations in domestic labor and the strength of family relationships. On the basis of these conclusions, four scenarios regarding baby boomers' domestic labor and caregiving in 10 years were proposed using two axes: the "high and low probability of alterations" and the "strengthening and weakening of family relationships." The first scenario is a "preference for the self-caring form of family," which has a high probability of domestic labor alterations and weak family relationships. The second scenario is a "preference for the flexible form of family," which has a high probability of domestic labor alterations and strong family relationships. The third scenario is a "preference for the traditional form of family," which has a low probability of domestic labor alterations and strong family relationships. The fourth scenario is a "preference for the public caregiving form of family," which has a low probability of domestic labor alterations and weak family relationships. These results provide basic information about the various aspects of baby boomers' lives-including the development of various goods and services, the establishment of policies regarding seniors, and programs for successful aging-and can help equip our society to take the actions needed for a super-aged population.

The $4^{th}$ industrial revolution is a super connection society. It connects all things between things and things, PC and mobile phone, human and human and human and things. In Jeju island, 'Batdam' and 'Sandam' are conneted like 'black dragon ten thousand Li', and stone walls are connected to each other as the stone network, which is called as the 'Goendam' (and conventionally is told as the 'Goendang') and is related to the Family network. Also, IoT(Internet of Things) makes the connection between the stone network and people. The Jeju's fourth industrial revolution is a its testbed. 'Goendang' connection in 4G industrial revolution is shown to be important Node and Link in socially and mathematically. In this paper, we review the historical background of the Goendang and find combinations of stones on the various types of stone field using the algebraic geometry.

This study explored the organization of high school Home Economics (HE) selective curriculum for the Fourth Industrial Revolution. We critically review the change process of HE curriculum as well as problems based on the understanding of the Fourth Industrial Revolution. The results were as follows. First, regarding the characteristic consistently shown in the revision process of high school curriculum, the huge increase of the number of subject organized resulted from the intensification of the selective-centered curriculum strengthening the choice for school and students. However, HE was reduced to some 'Technology-Home Economics' subject and a single subject 'HE Science' as a selective subject was subsequently combined with Technology after the $7^{th}$ curriculum period. Consequently, HE hard to organize the career-focused curriculum, emphasized by the revised 2015 curriculum due to the insufficient number of subjects. Second, the choice of HE in high school curriculum should be expanded as measures to organize the HE curriculum of high school to cope with changes that result from the Fourth Industrial Revolution. For the operation of the career-focused curriculum, career selective subjects and specialized subjects should be more diversely established. In accordance with changes in a future society that results from the Fourth Industrial Revolution, the HE education community should be prepared in advance to be organized as a selective subject when revising a subsequent curriculum, by newly establishing subjects necessary to students through collective intelligence and deliberation with pedagogists and scholars for subject content as well as by producing/getting approval from government-recognized textbooks.

The wave of democratization that started in southern Europe spread to South America and Asia, dismantling the Soviet Union and Eastern European countries and appeared as a Jasmine revolution in countries of North Africa and the Middle East. As a result, many scholars have actively carried out researches related to the sudden change of North Korea, while taking a cautious view that the Jasmine Revolution might occur in North Korea. The focuses of the studies were on the cause and timing of the sudden change and the main forces of the revolution in North Korea. There weren't enough discussions on how the process will be developed and whether there will be a system change. In this study, based on the results of analyzing the systematic changes of the Jasmine revolution nations, it suggested five scenarios that can be developed after the sudden change of North Korea. Scenario type I: Relatively peaceful and the possibility of regime change, Scenario type II: Reunification and then civil war, Scenario type III: Regime changed but one of Kim Il Sung family grabbing the power, Scenario type IV: Successful regime change but civil war happening, Scenario type V: Regime change failed and civil war continuing.

This paper examines how Sedgwick makes a political allegory of founding the nation in domestic terms in The Linwoods (1835). Set in the Revolutionary period, The Linwoods is a historical fiction reconstructed by the writer in order to diagnose currently controversial issues. In this aspect, Sedgwick's interest in history is genealogical in Foucaudian sense. Foucault's genealogical method provides a way of recuperating a part of history hidden, submerged, obliterated by the official history. Seen in a genealogical perspective, the story of the Linwoods can be viewed as a political allegory in order to explore political conflicts of Sedgwick's own day. Faced with the threat of national disunion presented in the Nullification Crisis of sectional conflicts and divisions, Sedgwick attempts to provide a fictional solution to the first serious challenge to the U. S. Constitution. Going back to the times around the American Revolution, Sedgwick emphasizes how strenuously the American Constitution of America was formed as the outcome of the war against the tyranny of Britain, and how the Union was made on the basis of the cooperation between the States. By posing a contrast of political positions between family members, Sedgwick imagines a family/nation that allows diverse political positions. The conclusion of a diversity of marriages between man and woman who agree to be united after overcoming their differences in political affiliations seems to show her conservative proclivity to support the Union. However, by emphasizing the principles of freedom and equality represented by the significant role of Isabella and Rose, an African-American slave, in the victory of the American Revolution, Sedgwick also supports the spirit of the Jacksonian American democracy.

Recently, during several years the number of ideal children have not changed at all. Because the most of Korean people considered that son is necessary absolutely for dependence in old age inheritance of family line and holding ritural and so on. Threfore, without revolution of value system for children we could no more expect to reduce fertility rate. The survey is intended to compare the characteristics between those women who want two or less number of ideal children and all married women(regardless the number of ideal children). The results showed as follows: The women who want small size of family were younger and little better educated than those of all married women. The age at marriage of women who want small size of family was older than that of all married women. The conducted rate of induced abortion and acceptance rate of contraception among those women who want small size of family were higher than those of all married women. The rate of those who want less than 2 children socalled ideal No. among all married women was 3.9 percent.
